NZ council rates have multiple components: the general rate (based on CV), UAGC (flat charge), and targeted rates (water, wastewater, stormwater, rubbish).

The UAGC is a fixed charge paid by all ratepayers regardless of property value — it reduces the share borne by higher-value properties. High-value properties pay more general rate but the same UAGC as a $300,000 property.
$/wk

For property investors, rates are a fixed cost that reduces gross rental yield. Lower-rate councils improve net yield.

Rates as a percentage of rental income is a useful normalised metric. Under 10% is generally manageable; above 20% puts significant pressure on cash flow. Remember rates increase annually — factor in projected growth when modelling investment returns.

How NZ Council Rates Are Calculated

New Zealand council rates are made up of several components that vary by council. Understanding each component helps explain why two properties of similar value in different cities can have very different rates bills.

The Capital Value used for rates is set by the council's valuation (not the market value), and is updated periodically — typically every three years.

Example: Auckland vs Wellington Rates Comparison

Same property CV ($750,000) in two cities

ComponentAuckland CityWellington City
General Rate ($2.48 vs $6.10 per $1,000 CV)$1,860$4,575
UAGC$462$620
Water / Wastewater$1,180$1,420
Other Targeted Rates$450$520
Total Annual Rates$3,952$7,135

Wellington's general rate per dollar of CV is 2.5x higher than Auckland's — a legacy of slower CV growth combined with significant infrastructure investment requirements. However, Auckland's median CV is much higher, so the absolute rates bills are closer than the rate differentials suggest.

Why Wellington Rates Are Higher

Wellington City has consistently among the highest rates in NZ relative to CV. Key reasons include:

NZ Rates Growth — What to Expect

NZ council rates have grown significantly faster than CPI inflation over the past decade. Average annual increases across major councils have been 5–8% per year, compared to 2–3% CPI. Key drivers include:

Property owners should budget for rates to increase by at least 5–7% per year when projecting ownership costs forward.

Frequently Asked Questions

Capital Value (CV) is the council's estimate of your property's market value at the last general valuation date. It is used to calculate your general rate. If your CV is $800,000 and the council's general rate is $4.00 per $1,000 CV, your general rate component is $3,200. CV is NOT the same as the current market value — CVs are typically set every 3 years and may be significantly below or above market value depending on when the last revaluation occurred.
Councils set their total revenue requirement each year (based on planned spending), then divide it across all ratepayers based on CV. If the council increases spending by 8%, rates increase by approximately 8% regardless of whether your specific property's CV changed. If your CV grew faster than the average in your council area, your share of the rates increases — but only if your CV grew relatively faster than others.
The UAGC (Uniform Annual General Charge) is a fixed annual charge paid equally by all ratepayers. It exists to ensure everyone contributes a baseline amount to council services regardless of property value. A higher UAGC relative to the general rate means lower-value properties pay proportionally more, while higher-value properties pay relatively less through the UAGC component. Councils balance these two components to achieve their equity objectives.
You can object to your property's Capital Value if you believe it is incorrect — contact the council or Quotable Value (QV) for the objection process. You cannot object to the rate itself (that is set through the Annual Plan process, which has a public submission period). If you believe you are being charged the wrong targeted rates (e.g., charged for water supply in an area without council water), contact your council directly.
